That's what worked for me
I was lost too, but I manipulated some things and found it. First of all, download the patcher v2.3 from the current thread that's up"
https://www.mpgh.net/forum/showthread.php?t=1377113 "... After you download it try to download in this thread the Lol mpeh.net.zip. Make sure to extract the Leauge of Legends.exe from the Lolmpeh.net.zip into this directory C:\Riot Games\League of Legends\RADS\solutions\lol_game_client_sln\release s\0.0.1.XXX\deploy.
Be cautious thought, if you copy paste the directory as it is it won't be searchable it's just an example. For instanse u must use this C:\Riot Games\League of Legends\RADS\solutions\lol_game_client_sln\release s\ and after that it will take u to a folder with the releases. Then go to the latest folder of 0.0.1.XXX and find the highest number folder of XXX's. Click on that. Click deploy. Delete the current Leauge of Legends.exe and replace it with the one from the zip "Lolmpeh.net.zip" and extract the patcher on desktop or whatever and then patch it. I had lol updating itself though once so if it randomly updates you have to do this all over again. If u have a question don't hesitate to ask
